Application filed October 30, 1924. Serial No. 746,807.

To all whom it may concern:

Be it known thatI, DONALD Evans PAR- RISH, a citizen of "the United States of America, and a resident of the city of Buffalo, in the county of Erie, in the State of New York, United States of America, have invented certain new and useful Improvements in Ash-Can Hoists, of which the followingjs the specification.

My invention relates to improvements 1n ash can hoists and the objectof the invention is to provide an improved construction of door operating mechanism as well as a counterweight mechanism.

A further object is to devise means for supporting the warning gong in the counterweight, said gong beingadapted to ring upon the sidewalk doors being opened or shut with the consequent movement of the counterweight. I

My invention consistsof an ash can hoist constructed and arranged all as hereinafter more particularly described'and illustrated in the accompanying drawing in which:

Fig. '1 represents a vertical section through the pit containing the hoisting gear.

Fig. 2 is a vertical section through the line 22 Figure 1.

Fig. 3 isa plan view showing the sidewalk doors open.

Fig. 4 is an enlarged vertical section through the counterweight showing the gong in position therein, and

Fig. 5 is aperspeotive detail of an end of the transverse channel which supports the hoist assembly, showing the same socured to gutter channels extending around the top of the pit.

Like characters of reference indicate corresponding parts in the different views.

1 is the pit in which the hoist assembly is mounted. 2 are angle members extending around the open top of the pit 1, said members being imbedded in the concrete or other material of which the pit 1 is made. 3 are gutter channels surrounding the top of the pit 1, said channels 3-positioned inside of the angle members2; 4.- is a channel member extending between the opposed gutter channels 3 and having its ends resting on the toe-pieces 5 which are secured to such gutter channels.

6 i the vertical stationary'mast for the hoisting gear, said mast secured at its bottom to .the bracketfi .which is'in turn secured to the interior face of one wall of the pit 1. 8 is the movable mast secured at its lower end to the sleeve'member 9 which is adapted to slide on the stationary mast 6.

10 is an inwardly extending bracket, secured to the inner face of the channel 4 and provided with a socket 11 adapted to secure the upper end of thestationary mast.

6 in place, said bracket 10 carrying'the u per blocks 12 of the mast hoisting gear, t e lower block 13 beingjournalled on the sleeve member 9 and the usual chain l'extending betweenthe blocks12 and 13.

15 is a depending bracket secured to the channel 4 upon which is journalled the pulley 16 over which extends the chain 17 which is connected at one end to the counterpoise 18 and at the other end to the sleeve 19 which extends freely around the stationary mast 6. i

The counterpoise 18 is hollow and the vertical slide 20 secured at its upper end to the channel and at its lower end to the bracket 7 extends freely therethrough. The counterpoise being adapted to slide on such slide member. 21 is a suitably positioned upper stop on the slide 11 and 22 is a lower stop. 23 is an upper spring switch nor: mally 1n engagement with the contact plate 24-wh1ch is suitably insulated from the counterpolse casing 18. A vertical pin 25 extends freely through the casing 18, being secured to an insulated portion ofthe spring switch 23.

26 is a lower spring switch'insul'ate'd from the counterpoise casing 18 and normally contacting with the contactv plate 27 also insulated from such casing.

28 is a vertical pin adapted to extend freely through the casing 18 and securedto an nsulated portion of the spring switch 26; 29 1s a wire extending between the two contact plates 24 and 26. 30 is a lead from the lower switch 26 to the vibrator coil 31 of the gong 32. 33 is a lead from the other terminal of the vibrator 31 to the batteries 34, and 35 is a 'Wire connecting the other terminal of the battery with the switch 23. o

36 are the sidewalk doors hinged to the angle members 2 and provided respectively at 'their'outer ends with the uard gates 37 and 38, the guard gate 37 being rigidly secured to its door 36 whereas the guard gate 38 ishinged to its door 36, the coacti ng edges ofthe gates 37 and 38.,preferably overpping a h w en. er r pir s' dw w pivotally secured together at thelr lower ends hew leer u a t ei i pp e f'ct lspf trah tar ts; t i am portions and the extremities "of such ends 40 being pivotally secured to the underneath sides of the doors 36. 41 are short chains s eeured together-.. a t

their upper ends in one or the links of the atiyefipe lti nithe leak 11m nv 4 i -21 111165 in the desired direction with the result that the sleeve 9, is raised and the movable mast 8 accordinglyelevated In the lowermost positionythe bottoin of tire-sleeve member 9 engages thesleeve 1'9 and as the sleeve member 9 is raised the sleeve 19 is accordinglyraised under the influence of the nounterpoise 18 with the resultthat such sleeve moyes from the dotted ,positionillustrated in g re 1 in o rep n own n. u lines in the samefigure When this occurs the rods. 39are gpushed upwardly, conseqiiently Opening the doors 36 the :full ex: tent until the portions j 4010f the rodsare in the position shown in full dines in Figure 1, the guard gates assumingi the position illustrated f-inf that afigure, -the hinge on the gate 38 being preferably a {spring {hinge tokeep the gate in its normal closed position. va a .As the =sleeve =l9 is niovedj up the -1nast 6 the counterpoise slides down they'slide member 20 andwhen the; sleeve i'is raised the full extent the {pin 2850f the switch 26 engages the lower, stop 22 011 the slide meniber 20 and thusthrows the lower spring switch out of contact with the plate 27, thus vbreaking theigong circuit, it being understoodv fthat the warning gong rings continually during the process ofmoving the hoistinggear and doors into their operative: position. c On pulling down the movable 'mast 8 by the inast hoisting gear 'the lower end of the sleeve nieinber 9 will engage the sleeve 19, sliding it downbn the stationary mast 6 and thus closing the doors 36 QVBrWhe op o he "descending movable -mastiand ash can hoisting gear. Immediately the sigev e is forced downwardly onth'emast h wa ms-111s wi .;;b. q ll iiigly raised tutti thus the pin 28 "will be thrown out of engagement with the stop 2,. fih J t h 26 iDQJi JF QHB lE Y 27,closing the gong oircuit and causing the tenements attestsewes-ulna a illustrated in dotted lines in Figure 1,
